X 2572. Condenser Testing Instrument.
Of the firms writing, Messrs Nalder Bros, Griffin & Sons, and Cambridge + Paul Co, have nothing to offer which would be suitable.
The GEC have a galvanometer at about £24 which is probably too large.
There remain Messrs W G.{Mr Griffiths - Chief Accountant / Mr Gnapp} Pye's induction coil & telephone outfit, of which the price is not quoted, and which may be thought too elaborate, and Messrs Gambrell's galvanometer at about £5 which would probably serve; though the deflections will be small.
Correspondence returned herewith.
Signed: F.{Mr Friese} J.{Mr Johnson W.M.} Allen.
This Sheet must be filed on completion of the work.
